### 5.2.17 Domain Literals: RFC-822 Section 6.2.3

A mailer MUST be able to accept and parse an Internet domain literal whose content ("dtext"; see RFC-822) is a dotted- decimal host address. This satisfies the requirement of Section 2.1 for the case of mail.

An SMTP MUST accept and recognize a domain literal for any of its own IP addresses.
